PR-186-9126-R01 Evaluation of Commercial Systems for Measuring Cathodic Protection

The objective of this research was to provide an evaluation of commercially available CP survey equipment used for measuring off-potentials on a pipeline. The objective was accomplished by a series of field evaluations on operating pipelines designed to provide a wide range of conditions for evaluating the instrumentation. The primary incentive for this research was to provide the participating PRC members with an evaluation of the off-potential measurement systems commercially available, such that a basis is established for considering and selecting the most appropriate equipment for their particular application.
